What are the disadvantages of industrial plug valves?

Plug valves for industries offer a lot of good benefits, from their simple design to how they can handle a diverse range of media. However, despite these optimistic behaviors, there are disadvantages that you must be aware of in order to avoid the gravest of issues in your workspaces. This knowledge base will tackle the following: 

– Features and uses of industrial plug valves

Industrial Plug Valves 101

In the world of industrial valves, the types are usually denoted out of their designs. In particularly, plug valves consist of a plug following the cylindrical or conical shape, which then rotates within the body to either block of allow the flow of your material through a port. 

The main features of an industrial plug valve are:

• Simple design and operation
• Fast operation
• Tight sealing
• Versatlity
• Corrosion and abrasion resistance
• Low flow resistance
• Easy maintenance
• Multi-port design

Along twith hese features are also the various uses of these valves, which are:

• For on-and-off control
• For throttling
• For handling corrosive and abrasive fluids 
• For high-pressure and high-temperature applications

Disadvantages of Industrial Plug Valves, Revealed!

This time, let’s take a look at what could make them unsuitable for your industry.

1. High Costs

Generally speaking, plug valves are more expensive than their counterparts. Industries may need to shell out more budget to have them. Honestly, this could be a significant barrier and hindrance for industries that want to scale up, but have limited financial resources. 

2. High-Maintenance

Sure, the aspect of easy maintenance is there, but this is relative. There are instances when plug valves will require regular and tougher maintenance to ensure they work at their very best. 

In particularly, the internal seals and bearings should be inspected, lubricated, and replaced regularly and perfectly well. Sometimes, the time spent for maintenance adds to the costs. 

3. Unsuited for Applications Where Precise Flow Control Is Needed

For why would you use a car with ordinary sets of wheels when driving uphill, such as during a hike? The same adage goes with your plug valves. They may not be most suitable for applications where precise flow control is needed. The reason is their limited throttling capabilities. However, they’re best for full-open or fully-closed positions. 

4. Improper Installation Leads to Damage and Leaks

Installing these valves improperly leads toward damage and leaks, but you don’t want this, since you’d like, as much as possible, for the valves to stay with you longer. Leaks can pose significant safety hazards and environmental concerns.

5. High Torque Requirements

In physics, torque refers to the rotational analogue of linear force. Torque is also pertained to as “the moment of force.” When it comes to your plug valves, the torque requirements are so high.

These valves often need high torque to operate full well, especially when used in partially open systems. You may need to spend more. 

Other disadvantages are limited flow capacity, sensitivity to abrasive fluids, and temperature sensitivity.
